  5. Product Lineup World-leading Disaster Recovery Solution for the Oracle SE database Affordable Alternative to GoldenGate: – Data Replication for Oracle-sourced databases

  6. Physical Replication “One on one” copy of the primary database in permanent recovery Use redo apply to keep up to date 100% binary copy, database are exact replicas Referred to as a standby database Best suited for DR Logical Replication Independent 2nd database in sync by replication mechanism Uses SQL statements to keep up to date Subset of data is replicated Cross version, cross platform Separate physical database structure Best suited for information sharing, migrations, real-time reporting etc Two Replication Types

  7. DisasterRecovery Disaster Recovery (DR) is seen as • Process • Policies • Procedures Established to ensure recovery and continuation of • Infrastructure • Applications • Databases All of which is critical to the Business Continuation

  8. Why Bother With Disaster Recovery? • Most critical asset of companies today: Database • Must be protected against disaster: • Hardware Failure • Human Error • Natural Disasters • To ensure business continuity • (93% of businesses that suffer significant data loss are out of business in 5 years – US Labor Department) Best way to protect your database AND your business: Standby Database

  9. Standby Database High Level Overview Redo Logs Archived Logs Archived Logs

  10. Dbvisit Standby • Physical data replication • “Oracle Data Guard” for Standard Edition • Easy to install, configure, use and manage • Creates the standby database • Support for RAC, OMF and ASM • Support for Oracle 8i forwards, EE, SE, SE One and XE • Broad OS compatibility • Oracle Linux, Oracle Solaris, Windows, AIX, HP-UX, VM • Cloud deployment on Amazon AWS

  11. Standby Database options • Data Guard (requires Oracle EE) • Do it yourself • sounds easier than it is • Third party products such as • Dbvisit Standby

  12. StandbyDatabase using Dbvisit Standby

  13. Dbvisit Standby Advantages • GUI or Command line interface • Same underlying architecture as Data Guard • Standby database is 100% copy, offload backups • Efficient using redo recovery Disadvantages • No support for cross platform, cross databases versions • At best standby is READ-ONLY (except with Active Data Guard) • Not selective in replication, all or nothing. • Failover is not done lightly

  14. Standby Database Features • Core Function – Send and Apply Redo • Creates the standby database automatically • Reporting standby database • Open Standby Read-Only • Internal Dbvisit Standby Reporting • Archive / Transfer log gap reporting • 20+ APIs • Resynchronize Standby Database • Missing or Corrupt archive logs not yet applied to standby • Nologging operations was performed on Primary

  15. StandbyDatabase Features Failover • Activates the standby database in the event of DR • Initiates a resetlogs (redo logs are created) • There is no going back (unless using flashback - EE) • Potential for dataloss Switchover(role reversal) • Is used for planned maintenance on primary server • Switches database roles • Increase availability on database • Small outage required • No data loss

  16. Favored by DBAs Our customers are DBAs Our products are built specifically for DBAs Make their life easier Do more on a limited budget Add real value to Oracle Standard Edition Our support is provided by DBAs Built by DBAs for DBAs

  17. Building your own DR Solution It seems easy so what is so hard about it? Accountfor the following: • Robustness, when all else fails this has to work • Completeness handle all Oracle errors and network failures • Differences in Oracle versions • Automatic continuation of log shipping when some nodes are down (RAC) • Documentation and training • Automation of creation of standby database • Complexities of ASM, OMF, RAC • Graceful switchover
